Thanks. Sorry been a very very long time since I used a Macintosh at college. Still trying to remember how to use it. I hadn't spotted the readme on the MacPack drive.
Edit: Having said that, when I double click on the readme icon on the MacPack drive I get a dialog saying "Sorry, a system error occurred. unimplemented trap" with a bomb icon and just a restart button. Perhaps my knowledge of Mac is too rusty
No worries! The readme just has a few notes on the pack including a brief bit about how to use the System Picker. All of the information in the readme file on the drive can also be found in the readme that comes in the MacPack .zip file, which itself links to the Google Doc with even more info.
Macs can be weird with text files and "file associations". It may just need you to open TeachText/SimpleText once so it knows to try using that for the file. I'll try and make sure the correct Preferences file is in place for the next release so the ReadMe will automatically open in some compatible application. I probably got overzealous in deleting prefs files before the last release.
As a more robust solution, try checking in MacPack:Utilities:Text/PDF:BBEdit for a pair of text editors which can read pretty much any of the text files on the drive. In System 7 you can drag the text file onto the BBEdit icon to open it. In the next image I'll have an alias on the desktop to make this easier.
Regarding System Picker, the way it works is it will scan for any bootable System drives and let you select which one you'd like to boot into. During this process it will "unbless" (make non-bootable) every other System folder it finds. As such, I strongly recommend not using System Picker if you have multiple drives mounted, as running it will unbless the bootable Systems on any additional drives, rendering them non-bootable until re-blessed.
Should this happen, blessing a system folder in classic Mac OS is generally just a matter of double-clicking to open the System folder you wish to bless for the drive, then double-clicking the System suitcase. If it worked, the containing folder should now show a Mac icon to indicate the drive is blessed / bootable.
